You may want a differential balanced preamp to bring out the best in Pass's balanced designs. I use an AtmaSphere MP-1 preamp with XA 160.8 monoblocks and a modified XP-25 phono stage. It sounds very clean and can be contoured to taste with tube rolling.
What tube pre-amps pair well with Pass amps?
Does anyone have experience with this? I'm running Focal Sopra No. 2s and I understand the Focal's pair nicely with Pass amps. Any tube pre-amps you'd recommend for consideration? I like the classical rock, but am gravitating more to jazz, classical and vocals. I just want to try something new. Thanks.
